Disable DHCP Server: Stop the router from issuing IP addresses to users connected to its LAN ports
Enable DHCP Server: Allows the router to issue IP Addresses to users connecting to its LAN ports.
Enabling this option allows you to configure the Router‘s Dynamic Host Configuration Protocol
(DHCP) server function. The DHCP server is enabled by default for the Router’s Ethernet LAN
interface.
The DHCP service will supply IP settings to computers which are configured to automatically obtain
IP settings that are connected to the Router through the Ethernet port. When the Router is set for
DHCP, it becomes the default gateway for DHCP client connected to it. Keep in mind that if you
change the IP address of the Router, you must change the range of IP addresses in the pool used for
DHCP on the LAN.
Start IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because
the default IP address for the Router is 192.168.1.1, the default Start IP Address is 192.168.1.2, and
the Start IP Address must be 192.168.1.2 or greater, but be equal to or smaller than 192.168.1.254.
End IP Address: End IP Address: Enter a value for the DHCP server to end with when issuing IP
addresses. The End IP Address must be smaller than 192.168.1.254. The default End IP Address is
192.168.1.254.
Leased Time (hour): The Leased Time is the amount of time in which a network user will be
allowed connection to the Router with their current dynamic IP address. Enter the amount of time, in
hours, then the user will be “leased” this dynamic IP address. After the dynamic IP address has
expired, the user will be automatically assigned a new dynamic IP address. The default is 24 hours.
Static IP Lease List: The function allows you to specify a reserved IP address for a PC on the LAN,
that PC will always obtain the assigned IP address each time it accesses the DHCP server. Reserved
IP addresses should be assigned to servers that require permanent IP settings. Click the Add Entries
button, and then you will set the rule in the screen as shown below
